Background Oral cancer is a major public health problem among Paniya tribes, a marginalized tribal group in Wayanad, India. Oral leukoplakia (OL) and oral submucous fibrosis (OSF) are the most common oro-mucosal diseases that have a very high malignant transformation.
The objective of this study was to evaluate the risks imposed by betel quid habits in the development of OL and OSF among Paniya tribes of Wayanad.

Materials and methods A cross-sectional descriptive study was conducted to assess betel quid habits and precancerous oral lesions prevalence among 600 Paniya tribes. Information on chewing status was collected from cases and controls using a questionnaire. The collected data were subjected to statistical analysis.

Results Precancerous lesions were found to be far more prevalent among chewing Paniya tribes than among the controls (P < 0.0001). The prevalence of OL and OSF was 12.9% and 13.02%, respectively among betel quid chewers. No OL and OSF recorded among non-chewers.

Conclusions Prevalence of precancerous oral lesions in the study population was due to betel quid usage and lack of awareness regarding the deleterious effects of the products used. There is an urgent need to develop and implement culturally appropriate awareness-raising activities to target betel quid habit.
